Hi Johnathan, I saw you made the update, however, it seems this wasn't enough as I still get the same build error. This time I also noticed a problem while building gnuradio so maybe the problem is somewhere else. Here is what I do (xubuntu 12.10 64 with gcc 4.6 and 4.7 installed): export CC=/usr/bin/gcc-4.6 export CXX=/usr/bin/g++-4.6 cmake -DCMAKE_INSTALL_PREFIX=/opt/gnuradio/v3.6.4.1-1146-gae625607-next -DENABLE_GR_ATSC=OFF -DENABLE_GR_CTRLPORT=ON .. Then I type make and it builds fine, however, if I just type make again (or make install for that matter) I get an error: alc@PC1927:~/sdr/gnuradio/v3.6.4.1-1146-gae625607-next/build2$ make [ 5%] Built target volk [ 5%] Built target test_all [ 5%] Built target volk_profile [ 6%] Built target pygen_python_volk_modtool_dad04 [ 6%] Built target pygen_python_volk_modtool_f7e51 [ 6%] Built target doxygen_target [ 6%] Built target pmt_generated Linking CXX shared library libgnuradio-pmt-3.7git.so make[2]: *** [gnuradio-runtime/lib/libgnuradio-pmt-3.7git.so.0.0.0] Error 1 make[1]: *** [gnuradio-runtime/lib/CMakeFiles/gnuradio-pmt.dir/all] Error 2 make: *** [all] Error 2 alc@PC1927:~/sdr/gnuradio/v3.6.4.1-1146-gae625607-next/build2$ Subsequent attempts at "make" are OK, but my application still fails to link. My application (https://github.com/csete/stlm/tree/master/receiver) is also built using cmake. I tried forcing it to gcc 4.6 instead of the default 4.7. It will then give a symbol name in the error message: /usr/bin/ld: CMakeFiles/strx.dir/strx/strx_source_c_impl.cpp.o: undefined reference to symbol 'pmt::intern(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' /usr/bin/ld: note: 'pmt::intern(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)' is defined in DSO /opt/gnuradio/v3.6.4.1-1146-gae625607-next/lib/libgnuradio-pmt-3.7git.so.0.0.0 so try adding it to the linker command line /opt/gnuradio/v3.6.4.1-1146-gae625607-next/lib/libgnuradio-pmt-3.7git.so.0.0.0: could not read symbols: Invalid operation collect2: ld returned 1 exit status make[2]: *** [strx] Error 1 make[1]: *** [CMakeFiles/strx.dir/all] Error 2 make: *** [all] Error 2 alc@PC1927:~/sdr/stlm.git/receiver/build$ Alex _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
